How to remove duplicate product tags in liquid arrays?

[GT5]

Hi,

I'm new with liquid and I have been trying to do an array with my product tags which I found how to do it. However, I would like to remove the duplicate. This is what I have, my if.. contains statement doesn't work.

{% assign tags = '' | split: '' %}
{% for product in collections.all.products %}

{%if tags contains product.tags %}
{%else%}
{% assign tags = tags | concat: product.tags %}
{%endif%}
{% endfor %}

I don't quite understand what you're doing here. You're assigning a string to a variable called tags with a split in it?

{% assign tags = " | split: " %}

{{ tags }}

// The above would output this string:
// | split:

You would like to remove the duplicate you said. Duplicate what? Your tags are already an array. You can loop through them:

{% for tag in product.tags %}
{{ tag }}
{% endfor %}

Or you can check them for a specific tag right away:

{% if product.tags contains 'long sleeve' %}
// do something
{% endif %}

Can you better explain what you're trying to do?

Hi,

Thank you for your reply! I was pushing all my tags in an array, however, there were rduplicate tags. But, I found out how to remove duplicate element by using :

{{ fruits | split: ' ' | uniq | join: ' ' }}
